Yeah my plan was o display the nanosecond range resulting in the
same tick value. That makes it a bit easier to compare the timings
to the data sheet. So maybe show both tick and ns range?

Ideally the timings would be from the device data sheet with
the latency added for components that are on the line in
addition to the device, such as level shifters and FPGA.
